PrepareForSegue Tableview issue

I have an issue with segue when clicking on cell and trying to transfer my date to DetailViewController

I didn't find here answers to my question, so I am asking here.

Here is my Method:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

//    NSLog(@"Source Controller = %@", [segue sourceViewController]);
//    NSLog(@"Destination Controller = %@", [segue destinationViewController]);
//    NSLog(@"Segue Identifier = %@", [segue identifier]);


        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
       if (indexPath){
        lastNews *item = [news objectAtIndex:indexPath.row];
        [segue.destinationViewController setDetail:item];
        NSLog(@"%@", item.title);

   }

}

if I will remove if condition only and leave my code like this one:

 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    //    NSLog(@"Source Controller = %@", [segue sourceViewController]);
    //    NSLog(@"Destination Controller = %@", [segue destinationViewController]);
    //    NSLog(@"Segue Identifier = %@", [segue identifier]);


            NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
            lastNews *item = [news objectAtIndex:indexPath.row];
            [segue.destinationViewController setDetail:item];
            NSLog(@"%@", item.title);



    }

my data can be transferred but only always first cell.

If I will implement it like this one:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {


    if ([[segue identifier] isEqualToString:@"detailNews"]) {
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
       //if (indexPath){
        lastNews *item = [news objectAtIndex:indexPath.row];
        [segue.destinationViewController setDetail:item];
        NSLog(@"%@", item.category);

   }

}

it will send but always a title of news and always from first news. (NSLOG only for checking)

I know it receives all values, I have checked it by NSLOG, not only the title.

For your information I have always latest 20 news parsed from web site That's working and my cells filled by news titles.

Could you please suggest me where I am wrong?

Thank you

Ok I think I solved my last issue. I have forgotten connect my IBOUTLET Tableview to my viewcontroller. That's it

if "sender" is the cell that's calling this, you can do:

NSIndexPath *indexPath = [[self tableView] indexPathForCell:sender];
lastNews *item = [news objectAtIndex:indexPath.row];
[segue.destinationViewController setDetail:item];
